DUlVIPING-WAGON.

Specification of Letters Patent.

Patented. May 14, 1907.

Application filed August 13, 1906. Serial No. 330,383.

To all whom it may concern.-

Be it known that 1, WILLIAM G. MAYER, a citizen of the United States of America, residing at Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Dumping-VVagons, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to certain new and useful improvements in dumping wagons, and the invention has for its object to provide a wagon having hinged drop doors or gates, and positive and reliable means for opening and closing the doors or gates from the forward end or drivers seat of the wagon.

To this end, my invention aims to reduce and equalize the power necessary to operate or elevate drop doors or gates, and to provide means whereby the above operation can be safely and expeditiously performed. In this connection, I have devised a simple and inexpensive wagon which will be strong and durable, and free from danger of injury by ordinary use.

WVith the above and other objects in view which will more readily appear as the invention is better understood, the same consists in the novel construction, combination and arrangement of parts to be presently described in detail and specifically pointed out in the appended claims.

Referring to the drawings forming part of this specification, like numerals of reference designate corresponding parts throughout the several views, in which Figure 1 is a side elevation of the hopper of my improved wagon, illustrating a portion of the running gear in dotted lines, Fig. 2 is a plan of the same, partly broken away, the hopper enlarging frame and drivers seat removed, Fig. 3 is a longitudinal sectional view of the hopper, the central portion thereof being broken away, Fig. 4 is a rear end view of the hopper, Fig. 5 is a detail perspective view of sheaves used upon the forward end of the hopper, Fig. 6 is an elevation of one of the worm drums used in connection with my wagon, Fig. 7 is a detail perspective view of a ratchet mechanism employed to operate the doors or gates of the wagon, and Fig. 8 is an elevation of one end of a door or gate, illustrating a hinge strap.

My invention resides entirely in the hopper of a wagon and the mechanism employed for raising and lowering the doors or gates thereof, consequently I use an ordinary form of running gear and brake mechanism which need not be shown or described in detail.

The hopper or body of the wagon consists of vertically disposed side walls 1 and 2 hav ing extensions 3 and 4, which support the door or gate operating mechanism of the wagon. The walls 1 and 2 are connected together adjacent to their rear ends by an inclined end wall 5, and at their forward ends by a similar wall 6. The side walls 1 and 2 are provided with vertically disposed strengthening cleats 7,, to the lower ends of which are connected angular hinge straps 8 and 9. Secured to the straps 8 and 9 by bolts and nuts 11 are doors or gates 12 and 14 adapted to fold inwardly and close the bottom of the hopper. The straps 9 have their lower or inner ends curved and are provided with eyebolts 15, which connect with chains or cables 16, 17, 18 and 19 employed for raising the doors or ates 12 and 14.

J ourna ed in the rear ends of the walls 1 and 2 is a tubular shaft 20, the one end of which protrudes through the wall 2 and is provided with a worm drum 21, said drum being fixed upon the shaft 20 by an eye-bolt 22. Centrally upon the shaft 20 is mounted I two worm drums 23 and 24 similar to the drum 21. Connected to the eye-bolts 25 of said drums are the ends of the chains or cables 18 and 19, whereby when the shaft 20 is rotated in the right direction, the chains will wind upon the drums 23 and 24 and elevate the doors or gates 12 and 14. To retain the chains or cables 18 and 19 in close proximity to the end wall 5, especially when the doors or gates 12 and 14 are open, I provide the end wall 5 with a guide strap 26 through which the chains 18 and 19 pass.

In the extensions 3 and 4, is journaled a tubular shaft 27, the one end of said shaft protruding through the extension 4 and carrying a worm drum 28, similar to the drums heretofore described. The drums 28 and 21 are provided with short chains or cables 29, which connect with the eye-bolts of said drums, and with each other by an adjustable connecting rod 30, said rod sliding in a guide bracket 31 carried by the side wall 2 of the hopper.

A conventional form of turn-buckle 32 constitutes the adjustable featurej of the rod 30.

Mounted centrally of the shaft 27 are two Worm drums 33 and 34 having eye-bolts similar to the previously described drums. These eye-bolts are connected to the chains 16 and 17, which pass over sheaves 35, journaled inbrackets 36, carried by the forward end wall 6 of the hopper.

Upon the shaft 27 contiguous to the GX-I tension 3 is mounted a ratchet wheel 37, and loosely mounted upon the shaft 27 is an operating lever 38 having a pivoted pawl 39 adapted to engage the ratchet wheel 37. The extensions 3 and 4 are connected together by transverse bars 40 which support a platform 41, and upon the platform 41 is mounted a drivers seat 42 and a foot rest 43. A bracket 44 is also supported by the platform 41 and in said bracket is pivoted a lockinglever 45 having a gravitypawl 46 engaging the ratchet wheel 37. The juxtaposition of the operating and locking levers with relation to the drivers seat 42 permits of a driver or operator easily manipulating said levers.

To enlarge the capacity of the hopper, I use a detachable rectangular frame 47 having inclined walls 43 and depending cleats 49 adapted to engage in keepers 50, carried by the side walls 1 and 20f the hopper. The frame 47 can be dispensed with at any desired time.

The manner of opening and closing the doors or gates of my improved hopper is as follows z-Assuming that the doors 12 and 14 are open as shown in Fig. 4, it is only necessary to oscillate the operating lever 38. As the lcver'38 recedes to secure a fresh hold upon the ratchet wheel 37 the pawl 46 of the locking lever 45 prevents a rearward rotation of the wheel 37. WVhen the shaft 27 and the drums 33, 34 and 28 are rotated, the chains or cables 17 and 16 are wound upon the drums 33 and 34, respectively, and the chain 29 is wound upon the drum 28. The chain 29 pulls forward upon the rod 30 unwinding the chain 29 from the drum 21, and since the chains 18 and 19 are reversely arranged relatively to the chain 29, the rotation of the shaft 20 will wind the chains 18 and 19 upon the drums 23 and 24. The weight of the doors or gates 12 and 14 will be equally distributed upon the four chains 16, 17, 18 and 19, and a positive co-operation of the shafts 20 and 27 is obtained through the medium of the flexibly and adjustably connected drums 21 and 28. The worm or spiral drums together with their connections, constitute the principal features of my invention.

To release the doors or gates 12 and 14, it is only necessary to move the lever 45 until the pawl 39 releases the ratchet wheel 37,

and then move the locking lever forward. The weight of the doors assisted by the contents of the hopper causes the doors to open by gravity.

From the foregoing description taken in connection with the drawings, it is thought that the novel coi'istruction and opm'ation of my improved wagon will be fully understood, and 1 wish it to be understood. that such changes in. the details of construction as are permissible by the appended claims, may be resorted to without departing from the spirit and scope of the invention.

W'hat I claim and desire to secure by Letters Patent, is

In a dumping wagon, the combination with a hopper embodying side walls having forwardiy projecting extensions, a front end wall, and a rear end wall connecting the side. walls, a plurality of vertically disposed strengthening cleats secured to the outer faces of the side walls, a pair of doors forming the bottom of said hopper, hinge straps connecting said doors to the lower end of said strengthening cleats, a tubular shaft 2()jour naled in the side walls in the r air of the rear end wall, worm drums 23, 24 carried by said. shaft centrally of the side walls, ewe-bolls passed transversely through said worm drums and the shaft and securing the drums to the shaft, a worm druni 21 carried on one end. of said shaft outside of the side wall, an eye-bolt securing said drum 2] to said shaft, a tubular worm shaft 27 journaled in the front extensions of said side walls having one end extended beyond one side wall, a worm drum 28 on said extended end of the shaft 27, an eye-bolt securing said drum 2% to said shaft, worm drums 33-34 arrangel'l. on saidv shaft 27 centrally of the side walls, eye bolls securing said drums 33 34 to said shaft, a pair of chains 16'1.7 connected at their one end to the. eye-bolts which secure the worm drums to the shaft 27, and at their other ends to the forward ends of said doors, sheaves carried by the front end. wall, over which said chains operate, a pair of chains 18- 19 connected at one end. to the rear ends of said doors and at tl'ieir other ends to the. eye-bolls which secure the worm drums 23-2 l to the shaft 20, a guide strap carried by the rear end wall for said chains 18, 19, a guide bracket carried by one of the side walls, a connecting rod Slltiflblj, mounted in said guide bracket,
